The Presonus Eris E5 active studio monitor offers a professional quality speaker at a price that everyone can take advantage of. By delivering an uncompromising output, which offers an honest and accurate response, rather than striving to compensate for poorer aspects of your mix, the Eris allows you to take total control over your sound when you're in the studio.
Presonus are renowned for crafting superb studio equipment, and the Eris E5 lives up to this reputation in style. The impeccably designed Kevlar low frequency transducer, and low-mass silk-dome tweeter require are powered effortlessly by the Class AB amplifier, which guarantees a crystal-clear response. The lightweight design makes monitor placement in the studio nice and simple.
The Eris E5 has built in Acoustic Tuning controls, which allows you to shape the response of each monitor to fit in with your own studio environment. On the rear panel you'll find an Input Gain knob, which determines the signal level before it reaches the internal power amplifier and enables you to perfect your gain levels for a smoother output. Mid and High control knobs, which allow you to shape the signal to suit your recording environment. Therefore, if you find that either the Mids - centred on 1kHz - or Highs are too powerful (or not powerful enough), you can attenuate the monitor output to create a sweetly balanced sound. Though the aim is to keep the settings as close to 0 as possible, you can add or cut by a huge -6db to 6dB range.
As well as the EQ section, there is a three way Acoustic Space switch, which controls a second-order, low shelving filter that cuts all frequency level below 800Hz by an amount of your choosing. Depending on your desired speaker placement, you have the choice of selecting presets of 0dB, -2dB or -4dB. The reason for this is to offset boundary bass boost that occurs when the monitors are placed near a wall or corner, a very useful feature that goes a long way to making things simpler when placing your speakers. Further control comes in the form of the Low Cutoff switch, which can be adjusted to roll off specified frequencies (80 or 100Hz) at -12dB/octave.
The prevalence of signal interference from various sources in a studio dictated Presonus' built-in speaker protection. With radio-frequency interference, electrical appliances, and heat all playing a part in causing signal degradation, certain measures have been taken to minimise any issues. RF shielding protects against radio frequencies becoming audible; over-temperature protection prevents heat-related issues. Current-output limiting prevents unwanted blowouts should a circuit short or cut out, whilst subsonic protection filters out extreme low frequency signals that could damage or affect the woofer's performance. Finally, the Eris E5 has a "soft start up" feature that prevents 'pops' that can occur when you power up the monitors.
The rear panel is home to a range of connectivity options including: a balanced XLR input; a balanced TRS input and an unbalanced RCA input. The balanced XLR and TRS inputs are perfect for minimising noise, but the range of options make it easier for you to connect whatever equipment you have easily.
It is clear to see that with the Presonus Eris E5 active studio monitor, the design team have excelled themselves. By offering a range of features that are normally associated with monitors carrying a heftier price tag, Presonus have opened things up significantly, once again delivering a high-performance product at an entry-level price. If you're looking for a pair of compact studio monitors that are simple to set up, easy to transport if needed, and above all sound absolutely stunning, then the Eris E5 is perfect.
